Beyonce sports new braided 'do as she celebrates fifth wedding anniversary with Jay-Z in Cuba

Beyonce and Jay-Z caused a big stir in Havana as they marked their fifth wedding anniversary on Thursday.

R&B's power couple were mobbed by dozens of well-wishers as they stepped out together to enjoy a celebratory lunch and sightseeing in the Cuban capital.

The 31-year-old singer cut a striking image, with her hair styled into cornrows.

She was wearing a patterned yellow ensemble which showed off her legs while rapper Jay-Z, 43, looked like the quintessential tourist in shorts, a blue T-shit and hat.

Power couple: Beyonce and Jay-Z stepped out in Havana, Cuba, on Thursday as they dined out for lunch to celebrate their fifth wedding anniversary

The couple - who married Paris on April 4, 2008 - toured colonial
Old Havana wearing dark glasses and were surrounded by bodyguards and
excited fans.

Beyonce posed for pictures with local schoolchildren while
Jay-Z puffed on a Cuban cigar, and then they popped into another
restaurant that boasts a rooftop terrace with a sweeping view of the harbour.

Beyonce and
Jay-Z declined to speak to reporters, and it was not clear why they
travelled to Cuba. State-run website CubaSi called it a tourist trip.

Washington's
51-year embargo makes it illegal for U.S. citizens to visit Cuba for
mere tourism, although tens of thousands of Americans travel there each
year on academic, religious, journalistic or cultural exchange visas.

The Obama administration eased many of the restrictions in 2011, but tourists still need a special visa or to be part of an organized tour.

In the past, artists who were challenged by the government have said
they visited for cultural purposes.

On Wednesday evening the pair dined
out at the renowned restaurant La Guarida - and police had to step in to
keep the crowds at bay.
